Abstract

Auditory-motor interaction is essential for the understanding of avian song learning and maintenance. The HVC is thought to be the most important station for auditory-motor integration in the avian song system. However, little is known about where and how auditory inputs are conveyed into the HVC. The shelf, a multi-auditory recipient region located along the ventral border of the HVC, is thought to be a possible source of auditory inputs to theHVC. Here, we investigated the functional neural connections between the HVC and surrounding area of the HVC including the shelf in zebra finch brainslices, using the real-time optical recording technique. Unexpectedly electrical stimulation of the shelf region did not induce signal propagation into the HVC, but stimulation within the HVC propagated strong signals into the shelf. These results suggest that the shelf is the region that receives output signals from the HVC, rather than a major source of auditory inputs to the HVC.
